Comments for Mask for high pressures

Yes at those high pressure settings you are more prone to leaks. It seems you may have found a mask that works but the issue is you have to make the headgear too tight. So before spending a lot of money try this cheaper alternative.

Try using a CPAP Mask Liner. They work well. The 2 types are:

a) Quietus Liners .... get the one with a tacking agent included with it. This is my first choice for you because of your high BiPAP settings.

b) Remzzzs CPAP Mask Liners.

Try them first. You must match the liner to the brand name and size of your CPAP mask.
